I'm experiencing phone freezing after using Spotify app. Typically, I am unable to unlock the phone for several minutes, until it recovers. Frequently, this happens to me when I open Spotify for a brief time (for some searching or checking), and then I exit.

I think this is a Spotify issue because problem seems to disappear when I kill Spotify process . I'm using this trick everytime I exit Spotify to avoid this inconvenient freezing.

Also, I'm noticing random Spotify lagging, as if there were connection problems, although Internet connection seems to be ok. For example, playlists don't load, songs don't play, searching doesn't show results.... It usually recovers, but then it fails again some minutes later.

Phone Sony Xperia Z1. Android 4.4.4. Spotify app: 2.2.0.636.

Thanks.
